Answer:
2(8x+1)+2(6x-4)
28x - 6
Step-by-step explanation:
2(8x+1)+2(6x-4)
16x +2 + 12x - 8
28x - 6
BI = BK bc bisecting it means cutting it in half
• f(x) = 5x + 5
• g(x) = 6x + 1
Now, you just sum those functions:
(f + g)(x) = f(x) + g(x)
(f + g)(x) = (5x + 5) + (6x + 1)
(f + g)(x) = 5x + 6x + 5 + 1
(f + g)(x) = 11x + 6
Therefore,
(f + g)(– 8) = 11 · (– 8) + 6
(f + g)(– 8) = – 88 + 6
(f + g)(– 8) = – 82 <——— this is the answer.
I hope this helps! =)
Answer:
The lower confidence limit of 99% confidence interval for the mean breaking strength of the briefcases produced today would be equal to 331.09 pounds.
Step-by-step explanation:
Lower limit of confidence interval = mean - Error margin (E)
mean = 341.0 pounds
sd = 21.5 pounds
n = 35
degree of freedom = n - 1 = 35 - 1 = 34
confidence level = 99%
t-value corresponding to 34 degrees of freedom and 99% confidence level is 2.728
E = t × sd/√n = 2.728 × 21.5/√35 = 9.91 pounds
Lower limit = 341.0 - 9.91 = 331.09 pounds
